One useful route is:
(hyscan) scanner -> polygonization -> facet-capable CAM system
We can demonstrate this for you. Among the companies offering facet
capable cam systems are:
- Cimitron, and
The nice thing about this route is that it requires relatively little
CAD-design interaction, and should have a short lead time (a day to
2 weeks at a guess). I am assuming that you would be satisfied with
3 axis milling.
